[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0025] Example 1

[0026] In a preferred embodiment 1 of the present invention, a duct machine is provided, specifically, Figure 1 An optional structural schematic diagram of the duct machine is shown, such as Figure 1 As shown, the duct machine includes:

[0027] The duct machine body 1 is located inside the suspended ceiling of the room where the duct machine is located;

[0028] The first ventilation duct 2 is connected to the duct machine body 1 and is vertically arranged in the indoor wall;

[0029] The first air outlet 3 is located on the side of the ceiling;

[0030] The second air outlet 4 is located at the bottom of the ceiling;

[0031] The third air outlet 5 is located at the lower part of the first ventilation duct 2;

[0032] The fan 6 is located inside the air duct machine body 1, and is used to introduce air from the first air outlet 3 to flow toward the second air outlet 4 and the third air outlet 5 in the heating mode, or to introduce air from the first air outlet 3 and the second air outlet 4 to flow toward the third air outlet 5; in the cooling mode, introduce air from the third air outlet 5 to flow toward the first air outlet 3 and the second air outlet 4, or to introduce air from the second air outlet 4 and the third air outlet 5 to flow toward the first air outlet 3.

[0033] Optionally, the vertical ventilation duct is connected to the indoor ground; the third air outlet 5 is located at the connection between the vertical ventilation duct and the indoor ground.

[0034] In the above embodiment, the duct unit has three air outlets, and air is taken in and out from different air outlets during cooling and heating, respectively, so that cold air (during cooling) or hot air (during heating) can be evenly covered in the entire room. This effectively solves the problem of uneven air supply in existing duct units. Moreover, regardless of cooling or heating mode, air is taken in or out through two air outlets, so that cold air (during cooling) or hot air (during heating) can be quickly covered in the entire room. Therefore, the duct unit of the present invention has uniform air supply and can quickly cool or heat, and has a better heat exchange effect.

[0035] As a preferred embodiment of the present invention, other air outlets may be provided according to air supply requirements, and air inlet and outlet may be achieved through multiple air outlets, resulting in a better air supply effect.

[0036] In the above-mentioned embodiments, as long as it can be achieved that in the heating mode, the air introduced from the first air outlet 3 flows toward the second air outlet 4 and the third air outlet 5, or the air introduced from the first air outlet 3 and the second air outlet 4 flows toward the third air outlet 5; in the cooling mode, the air introduced from the third air outlet 5 flows toward the first air outlet 3 and the second air outlet 4, or the air introduced from the second air outlet 4 and the third air outlet 5 flows toward the first air outlet 3, the effect of uniform air supply can be achieved.

[0037] As a preferred embodiment of the present invention, the duct machine further includes: a second ventilation duct connected to the second air outlet 4, and arranged horizontally or vertically in the duct machine body 1; wherein, in the cooling mode, the second ventilation duct is arranged horizontally, and the second air outlet 4 is located on the right side of the second ventilation duct; in the heating mode, the second ventilation duct is arranged vertically, and the second air outlet 4 is located at the bottom of the second ventilation duct. wherein, when the air introduced from the first air outlet 3 flows toward the second air outlet 4 and the third air outlet 5, the second ventilation duct is arranged vertically; when the air introduced from the first air outlet 3 and the second air outlet 4 flows toward the third air outlet 5, the second ventilation duct is arranged horizontally; when the air introduced from the third air outlet 5 flows toward the first air outlet 3 and the second air outlet 4, the second ventilation duct is arranged horizontally; when the air introduced from the second air outlet 4 and the third air outlet 5 flows toward the first air outlet 3, the second ventilation duct is arranged vertically.

[0038] Among them, the second ventilation duct includes: a first air guide plate 7, located on the right side of the second air outlet 4; a second air guide plate 8, arranged on the left side or upper part of the second air outlet 4; wherein, when arranged on the left side of the second air outlet 4, it forms a vertically arranged second ventilation duct together with the first air guide plate 7; when arranged on the upper part of the second air outlet 4, it forms a horizontally arranged second ventilation duct together with the first air guide plate 7.

[0039] The duct machine further comprises: a partition 9 horizontally arranged inside the duct machine body 1; wherein the fan 6 is arranged on the upper part of the partition 9, and the second air guide plate 8 is pivotally connected to the partition 9. wherein the heat exchanger 10 is located on the left or right side of the fan 6.

[0040] Figure 1 The schematic diagram of the air inlet and outlet of the duct unit during cooling is also shown. Figure 1 As shown, the ducted air conditioner inhales air from the third air outlet 5, and the internal air guide plate turns to Figure 1 In the horizontal position shown, the air sucked in from the third air outlet 5 is cooled by the heat exchanger 10, passes through the fan 6, and then blown out from the first air outlet 3 and the second air outlet 4 respectively.

[0041] Figure 2 The figure also shows the air inlet and outlet diagram of the duct unit when heating. Figure 1 As shown, when heating, the fan 6 of the duct air conditioner switches the blowing direction, sucks air from the first air outlet 3, and the internal air guide plate turns to Figure 2 In the vertical position shown, the air sucked in from the first air outlet 3 passes through the fan 6, is heated by the heat exchanger 10, and then blown out from the second air outlet 4 and the third air outlet 5 respectively.

[0042] Therefore, during cooling, cold air is blown out from the first air vent 3 and the second air vent 4 at the ceiling position and sinks, and the air with a relatively high temperature at the bottom of the room is then drawn in from the third air vent 5 on the ground, so that the cold air quickly and evenly covers the entire room; during heating, hot air is blown out from the third air vent 5 on the ground and the second air vent 4 at the ceiling position, and the air with a relatively low temperature in the upper part of the room is then drawn in from the first air vent 3, so that the hot air quickly and evenly covers the entire room.

[0043] Compared with the air duct machine with only the first air outlet 3 and the third air outlet 5, the air duct machine with three air outlets has an additional second air outlet 4, and the air inlet and air outlet directions of the three air outlets are automatically switched according to cooling and heating. After the second air outlet 4 is added, during cooling, the space below the second air outlet 4 can also blow out cold air quickly, avoiding the uneven distribution of cold air caused by only the first air outlet 3; during heating, the space below the second air outlet 4 can also blow out hot air quickly, avoiding the uneven distribution of hot air caused by only the third air outlet 5.

[0044] In addition, according to Figure 1 and Figure 2 As shown, no matter it is cooling or heating, most of the air after passing through the fan 6 flows to the first air outlet 3 and the third air outlet 5, and the wind blown out of the second air outlet 4 is relatively gentle (small air volume), so people in the area below the second air outlet 4 will not feel strong wind and uncomfortable.

[0045] In addition, the duct air conditioner can also be set as follows: when cooling, air is discharged from the first air outlet 3, and air is taken in from the second air outlet 4 and the third air outlet 5; when heating, air is discharged from the third air outlet 5, and air is taken in from the first air outlet 3 and the second air outlet 4; this can increase the air intake range, and also allow cold air or hot air to quickly and evenly cover the entire room.

[0046] The fan 6 of the present invention includes the following two modes:

[0047] 1. The fan 6 includes a rotating device connected to the fan 6 and used to control the rotation of the fan 6; wherein, in the heating mode, the air inlet of the fan 6 is controlled to be toward the first air outlet 3, and in the cooling mode, the air outlet of the fan 6 is controlled to be toward the first air outlet 3, that is, the air inlet is toward the opposite direction of the first air outlet 3.

[0048] 2. The fans 6 include: a first group of fans 6 , the air inlets of the first group of fans 6 face the first air outlets 3 ; and a second group of fans 6 , the air outlets of the second group of fans 6 face the first air outlets 3 .

[0049] Example 2

[0050] Based on the duct air conditioner provided in the above embodiment 1, a duct air conditioner control method is also provided in a preferred embodiment 2 of the present invention, and the control method can be directly applied to the above duct air conditioner. Specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S302-S304:

[0051] S302: Detecting the operation mode of the duct unit; wherein the operation mode includes at least a cooling mode and a heating mode;

[0052] S304: Control the operation of the fan and the rotation of the second air guide plate according to the operation mode, so that in the heating mode, the air is introduced from the first air outlet to flow toward the second and third air outlets, or the air is introduced from the first and second air outlets to flow toward the third air outlet; in the cooling mode, the air is introduced from the third air outlet to flow toward the first and second air outlets, or the air is introduced from the second and third air outlets to flow toward the first air outlet.

[0053] In the above embodiment, the duct unit has three air outlets, and air is taken in and out from different air outlets during cooling and heating, respectively, so that cold air (during cooling) or hot air (during heating) can be evenly covered in the entire room. This effectively solves the problem of uneven air supply in existing duct units. Moreover, regardless of cooling or heating mode, air is taken in or out through two air outlets, so that cold air (during cooling) or hot air (during heating) can be quickly covered in the entire room. Therefore, the duct unit of the present invention has uniform air supply and can quickly cool or heat, and has a better heat exchange effect.

[0054] Among them, the rotation of the second air guide plate is controlled according to the operation mode, including: when the air is introduced from the first air outlet to flow toward the second air outlet and the third air outlet, the second air guide plate is set at the left side of the second air outlet; when the air is introduced from the first air outlet and the second air outlet to flow toward the third air outlet, the second air guide plate is set at the upper part of the second air outlet; when the air is introduced from the third air outlet to flow toward the first air outlet and the second air outlet, the second air guide plate is set at the upper part of the second air outlet; when the air is introduced from the second air outlet and the third air outlet to flow toward the first air outlet, the second air guide plate is set at the left side of the second air outlet.

[0055] According to different fan settings, in a preferred embodiment of the present invention, the operation of the fan is controlled according to the operating mode, including: controlling the rotating device to drive the fan to rotate; wherein, in the heating mode, the air inlet of the fan is controlled to face the first air outlet, and in the cooling mode, the air outlet of the fan is controlled to face the first air outlet.

[0056] In another preferred embodiment of the present invention, the operation of the fans is controlled according to the operation mode, including: in the heating mode, controlling the first group of fans to turn on; in the cooling mode, controlling the second group of fans to turn on.

[0057] Example 3

[0058] Based on the duct machine control method provided in the above embodiment 2, a storage medium containing computer executable instructions is also provided in a preferred embodiment 3 of the present invention. When the computer executable instructions are executed by a computer processor, they are used to execute the duct machine control method as described above.

[0059] In the above embodiment, the duct unit has three air outlets, and air is taken in and out from different air outlets during cooling and heating, respectively, so that cold air (during cooling) or hot air (during heating) can be evenly covered in the entire room. This effectively solves the problem of uneven air supply in existing duct units. Moreover, regardless of cooling or heating mode, air is taken in or out through two air outlets, so that cold air (during cooling) or hot air (during heating) can be quickly covered in the entire room. Therefore, the duct unit of the present invention has uniform air supply and can quickly cool or heat, and has a better heat exchange effect.
